How do I fix the code P0420 on my toyota?
Examine the exhaust system for damage and leaks. Pay close attention to the exhaust manifold, gaskets, and exhaust pipes pre-catalytic converter. If any leaks are found, repair the leak, clear the code, and complete several drive cycles to verify that was the fix.
What does Engine code P0345 mean?
camshaft position sensor
What Does P0345 Mean? The camshaft position sensor located in the internal combustion engine monitors the position and rotational speed of the camshaft. When the trouble code P0345 is set, the ignition spark and fuel injector timing fail due to the engine not knowing when to fire these components.
What is code P0420 toyota?
Error code P0420 – or Catalyst System Efficiency Below Threshold (Bank 1) – is one of several trouble codes that fall into the general exhaust system code block. P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system.

Where is the P0420 sensor on a car?
P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system. On most vehicles, there is an O2 sensor both in front (upstream) and behind (downstream) the catalytic converter. Normally, these two O2 sensors will have different readings when the car is running.
What does P0420 mean on a catalytic converter?
P0420 means that the efficiency of the catalytic converter is below the threshold. The ECM uses two O2 sensors, one in the front and one in the back of the catalytic converter to measure the efficiency. If the efficiency is low, the P0420 code will be triggered.
